Structural and photophysical properties of lanthanide complexes with N-(diphenylphosphoryl)-4-methylbenzenesulfonamide

New Luminescent Lanthanide Tetrakis‐Complexes NEt4[LnL4] Based on Dimethyl‐N‐Benzoylamidophosphate

“…To gain the exact reason of such a shift the low temperature X-Ray measurements are required. A similar redshift of the luminescence bands was earlier observed for SAPh based complex Na[Eu(PMSP) 4 ], [23] but in the case of the complexes with HPMSP ligand this shift was not so significant, moreover, it was observed for the europium complex only. Based on luminescence spectrum and measured 5 D 0 luminescence lifetime of NEt 4 [EuL 4 ] the radiative lifetime of 5 D 0 state (τ RAD ) and 5 D 0 intrinsic quantum yield (Q Ln Ln ) were calculated for the complex using the following Eqs.…”

“…In 2018 the first examples of triboluminescent CAPh based lanthanide tetrakis‐complexes were reported [12] . The lanthanide(III) tetrakis‐complexes with the general formula (cation)[Ln(Lig) 4 ] (where Lig − =β‐diketonate or SAPh − or CAPh − ) have been extensively studied recently [13–34] . In their structure, a lanthanide ion is surrounded by four ligands forming a LnO 8 environment and the cationic counterparts are typically alkali metal ions or positively charged N, P‐organic cations.…”

Spectroscopy and structure of [LnL3bipy] and [LnL3phen] complexes with CAPh type ligand dimethylbenzoylamidophosphate

“…Such the shift also was observed earlier for tetrakis-complexes with N-(diphenylphosphoryl) -4-methylbenzenesulfonamide (HPMSP) [18]. It is known that the position of 5 D 0 -7 F 0 transition band can be used for evaluation of nephelauxetic effect and the band shift with respect to gaseous Eu III reflects either an increase in the metal-ligand bond covalence or a decrease in the effective nuclear charge on the metal ion upon complexation.…”

Synthesis and Characterization of Anionic Lanthanide(III) Complexes with a Bidentate Sulfonylamidophosphate (SAPh) Ligand

“…Additionally, some tetrahedral distortion is observed. The Eu–O distances (Table ) were found to be in the range of 2.352(2)–2.493(2) Å for 1-Eu-293 and 2.336(2)–2.484(2) Å for 1-Eu-100 , being comparable with those of related complexes. ,, The Eu–O­(P) bonds (O1 and O6 atoms for 1-Eu-293 and O3, O8, O13, and O18 atoms for 1-Eu-100 ) are shorter compared to Eu–O­(S) (Table ) because of the higher affinity of the phosphoryl group to the lanthanide ion. Tetraethylamonium cations are located in the outer sphere, and the balance is the charge of the anionic complex molecules.…”

“…Moreover, the electronic structure of a ligand can be tuned by varying the substituents near the functional chelate core, which gives a valuable tool for the elaboration of “effective antennae” systems. It was shown that Ln-SAPh complexes exhibit relatively efficient ligand-to-metal energy transfer and strong metal-centered emission, which makes them potentially useful as effective energy converters. , …”
